1.1 What is the IZAR CENTER?
The IZAR CENTER is an M-Bus level converter / repeater, which as “memory” variant can
also be used as M-Bus master. In addition to reading M-Bus devices automatically and
independently, the memory variant can also monitor the data read out and react to alarm
conditions. The meter data stored in the IZAR CENTER can also be cyclically uploaded to an
FTP server.
1.2 What is the M-Bus?
The M-Bus (Meter Bus) is an inexpensive bus system used for reading resource meters,
such as water meters, heat meters and electricity meters. The M-Bus was developed by
Prof. Ziegler at Paderborn University in cooperation with the companies Texas Instruments
and Techem. It has been adopted as the European standard for all meters except electricity
meters.

The variants without memory can be used for the following purposes:
•Direct reading of M-Bus devices via a PC/laptop
•As repeater for connecting more than 250 M-Bus devices to an M-Bus network
or if the M-Bus lines are to bridge large distances (several kilometers)
The variants with memory offer the option of reading M-Bus devices automatically at
adjustable intervals, storing the data and sending this data over the interfaces on request.
The collected data can also be automatically uploaded to an FTP server. The IZAR CENTER
must be connected via the LAN interface or a special GPRS modem for this purpose.
An IZAR CENTER with memory can also monitor the M-Bus devices during automatic
reading and send an alarm report and/or alarm action in the event of an error.

2 Installation
2.1 Power supply
The IZAR CENTER is equipped with a universal power supply and can be operated with
mains voltages of 110 – 230 V AC (50..60 Hz).
2.2 M-Bus
2.2.1 M-Bus output
These terminals can be used to connect one or more pairs of wires to M-Bus devices. A
standard telecommunications cable can be used as M-Bus cable. The connection is not
polarity conscious. The maximum number of M-Bus devices that can be connected to an
IZAR CENTER depends on the type of IZAR CENTER used. See Table 1-1
The following types of connection are permitted:
•Star topology
•Bus topology
•Combination of bus and star topology
2.2.2 M-Bus input (Slave-In)
The M-Bus input is only intended for an IZAR CENTER without memory. An M-Bus signal
source (e.g. another IZAR CENTER or IZAR CENTER Memory) can be connected to this
input. All signals at this input to the IZAR CENTER are passed direct to the M-Bus output at
the same speed.
This makes it possible to connect several IZAR CENTERs in succession for reading more
than 250 M-Bus devices or if the M-Bus cable network contains excessively long lines.
Connecting several IZAR CENTERs in succession is called a cascade connection. A
cascade connection enables an M-Bus network to be expanded to any desired size.

Fig. 2-1 M-Bus cascade connection
Please note: Only one IZAR CENTER Memory can be used in a cascade connection. This
must then be placed at the start of the signal chain (see Fig. 2-1 M-Bus cascade connection
2.3 USB
The IZAR CENTER has a USB interface (USB B-socket) on the bottom side of the device for
direct connection to a PC/laptop. It is not necessary to install a special driver before
connecting.
Please note:
If you use Windows XP, you must remove the USB connector after the PC has recognized
the device and then reinsert the connector (this is only necessary once).
2.4 LAN
The LAN connection (RJ-45 socket) is located on the top side of the IZAR CENTER.
Use this connection if you want to read out the IZAR CENTER via TCP/IP. In addition to
direct reading/ configuration of the IZAR CENTER and the M-Bus devices, the IZAR
CENTER can automatically export data to an FTP server and send e-mails as alarm
messages.
The LAN connection supports dynamic IP address allocation (DHCP) and can also be
configured with a static IP address. Use the IZAR CENTER software for configuration of
these settings.
DHCP is activated by default. This means that the IZAR CENTER automatically attempts to
get an IP address. In this case, it is not clear which IP address the IZAR CENTER has been
assigned by the IT system. If you wish to find your device in the PC network, you can use the
TCP/IP search in the IZAR@CENTER software.
It is naturally also possible to connect the IZAR CENTER direct to the PC via a LAN cable,
but suitable static IP addresses must be assigned to the PC and the IZAR CENTER for this
purpose.
Please note: Connect the LAN connection of the IZAR CENTER before inserting the mains
plug.

2.5 Serial
The serial (RS232) interface can be used either for the direct connection of a PC or for
connecting a modem. The two functions cannot be used at the same time. Use the IZAR
CENTER software for setting the use of the serial interface.
2.5.1 RS232 – PC
If the serial interface is set to “PC” mode, you can connect the IZAR CENTER direct to a PC.
You do not need to install a driver on the PC.
Interface speeds (baud rates) of 300…57600 bauds can be used for communication with the
IZAR CENTER.
Baud rates of 300…9600 bauds can be used for communication with M-Bus devices.
Please note: At baud rates > 9600 bauds, communication signals are not passed through to
the M-Bus outputs (no communication with M-Bus devices).
The IZAR CENTER automatically detects the baud rate used (setting is not necessary).
2.5.2 RS232 – modem
If the serial interface is set to “Modem” mode, you can connect a modem to the IZAR
CENTER.
You can use the following types of modem:
•Analogue modem
•GSM modem
•GPRS modem
Attention: To ensure full and reliable operation, please use only modems specified by
HYDROMETER (see Suitable types of modem). No support is available for other types/models of
modem.

3 Configuration
3.1 Principles
3.1.1 Basic operation/architecture
As already mentioned above, an IZAR CENTER without memory serves only as a level
converter /repeater. The operation of this type is therefore relatively simple compared with
the IZAR CENTER Memory. As an IZAR CENTER Memory is equipped with functions like
automatic reading of M-Bus devices and parameter monitoring/alarm handling, it works with
internal lists. The following figure shows the architecture:
Automatic M-Bus

Alarm functions
Device list/ limits
(max. 1000 devices)

[email protected] · www.hydrometer.de 11
The IZAR CENTER requires 4 internal lists:
•Device List: Contains the information indicating which M-Bus devices are to be read and
how often, and optional alarm limit values.
•Address List: This list is comparable with an address book and contains the name, e-
mail addresses and telephone numbers of persons to be notified in the event of an
alarm.
•Text List: Freely definable texts that are to be sent in addition to the measurement data
in an e-mail or SMS in the event of an alarm.
•Action List: The IZAR CENTER can send a command to an M-Bus device in the event
of an alarm. This list defines which device is to be addressed if an alarm occurs and
which command is to be sent to the device.
Only the Device List is required for recording readings. All four lists are required if you wish
to use all the alarm monitoring functions of the IZAR CENTER. If you only want to send an
SMS or e-mail as alarm notification, the Action List is not necessary.
How to create and manage the respective lists is described in Chapter 3.3.1.
3.1.2 Installing the IZAR@CENTER software
Install the IZAR@CENTER software. This software can be found on the enclosed
HYDROMETER system software CD and on the HYDROMETER website:
http://www.hydrometer.com/systems/download.html
The website contains the latest version of each software.
The PC must fulfil the following system requirements:
•Pentium PC, 500 MHz or higher
•At least 256 MB RAM
•Approx. 50 MB of free hard disk space
•Operating system: Windows XP/Vista
•Free RS232 interface (if IZAR CENTER is to be connected direct to PC or read
via modem)
•Free USB interface (if IZAR CENTER is to be connected direct to PC )
•LAN interface (if IZAR CENTER is accessible via LAN)
You need local administrator rights on the PC during the installation.
After the installation, you will see a new program link with the icon on your desktop and in
the Windows Start menu.

Location Address may be used as system or plant identifier. The usage of the location
address is optional and serves merely for better identification of the system (if device is
connected via USB location address will be displayed as trailing addition to the USB
identifier in the connection setting field of IZAR@CENTER software)
The Period to read is part of settings fort he memory readout and is described in 3.4.1
3.1.5 Reading device list
This operation is optional and only makes sense if you have already written a device list into
the IZAR CENTER.
•Press the
button (Read internal status values and device list).
•The existing device list is shown in the program.
3.2 Reading devices direct
3.2.1 Standard M-Bus devices
There are two ways of reading the devices connected to the M-Bus output direct and
immediately. Entering the M-Bus address direct or reading with the aid of a device list. Direct
entry is faster. If several different devices are to be read, using a device list is the better
alternative, but a device list must be created first (see 3.3.1). The first way is briefly
described below.
•First select the “General: Read device” program view by pressing the button.
•Select the M-Bus baud rate to be used (see figure). This baud rate is usually either
300 bauds or 2400 bauds
•Now enter the M-Bus secondary address of the device to be read in the “Secondary
address” field. The secondary address is an 8-digit number and is shown on the
housing of most M-Bus devices. Press the button (General: Read with secondary
address).
Alternatively, you can enter the primary address of the M-Bus device in the “Primary
address” field, if known. If only one M-Bus device is connected, you can also use the
M-Bus broadcast address (“254”) here. In this case, press the button (General:
Reading using primary address) after entering the address.
•Wait until the M-Bus device has been read. If the reading process was successful,
the device data are shown in the data read field in the bottom right corner of the
window:

If the device was not read successfully, this can have several causes. Possible
causes of failure and their clearance are shown at 5.1 (M-Bus devices
•).
•If desired, you can add the device found to the device list if the reading process was
successful. This is done by pressing the button (General: Add found devices to
device list).
3.2.2 HYDROMETER M-Bus radio receiver
If you use HYDROMETER M-Bus receivers in your system, you can also configure and read
these devices with the IZAR@CENTER software. For this purpose, you must first select the
M-Bus receiver key in the program settings. Proceed as follows:
•Click the
button (Settings). The IZAR CENTER Settings window appears.
•Select the “Default 868 MHz Receiver Key” option at the bottom right if you use
the standard radio key in your radio network. If you use another radio key, select
the “868 MHz key” option and enter the radio key you use to operate your
HYDROMETER radio system in the input field on the right of the option.
•Close the window by pressing OK.
•A new view icon is now shown in the main window.
Proceed as follows to read or configure a connected M-Bus receiver:
•Change to the M-Bus 868 MHz radio receiver view. This is done by pressing the
button or ALT+5 keys.
•If several receivers are connected to this M-Bus network, enter the 8-digit M-Bus
address of the receiver you would like to connect to in the radio receiver address
field. The address is printed on the receiver.
If only one radio receiver is connected, it is not necessary to enter an address.
•Press the
button (Read internal state values) to connect the M-Bus receiver.
Alternatively, you can use the button (Read internal status values and device
list). The receiver’s list of received devices is then read in addition to the status
values of the receiver.

•If you would like to transfer devices from this list to your device list, click (Add
found devices to device list). A new dialogue box appears:
Select either “All devices found” or “Only selected devices”to transfer the
devices to the IZAR CENTER device list. If you wish to add several or only
certain devices, you can also select the devices beforehand in the M-Bus
receiver device list. As familiar from other applications, use the ×or Ctrl key if
you wish to select several devices from the list.
•Press the OK button to transfer the devices to the IZAR CENTER device list.
•The IZAR CENTER device list now contains the newly added devices.
3.3 Reading devices automatically
As described above, your IZAR CENTER Memory needs a device list to be able to read M-
Bus devices automatically and record and monitor their data. This list contains several items
of information:

•Which devices are to be read (e.g. device type)?
•How often is the device to be read (reading interval)?
•Name of device in plain text, for easier identifying of this device.
•Which M-Bus baud rate is to be used to address the device?
•How often is a reading process to be repeated in the event of an error?
•Which values of each device are to be monitored and what action is to be taken
in the event of an alarm?
The first step is to create a device list. There are several possibilities for this:
•Automatic M-Bus device search (recommended, see 3.3.1.1)
•Manually searching, finding and adding of M-Bus devices (see 3.3.1.2 Manual
device search)
•Manual adding of devices to the device list (see 3.3.1.3 Manually adding a device
•)
•Loading an existing device list from a file (see 3.3.1.4 Importing device list from a
file)
3.3.1 Creating a device list
3.3.1.1 Automatic device search
If you have never created a device list before or if you are taking a new system into
operation, the automatic device search is recommended. Here the PC software searches for
all possible M-Bus addresses and shows the M-Bus devices found on completion of the
search. Note that a few M-Bus devices do not support a device search.
The duration of an automatic device search mainly depends on the number of devices
connected, the M-Bus baud rate and the type of connection to the PC. A device search over
a modem connection can take a very long time and is therefore not recommended for large
systems.
The following steps are necessary to create a device list using a device search:
1. Set up a connection to your IZAR CENTER (see 3.1.4 Connecting to the IZAR
CENTER
2. Change to the view (Read device).
3. Click the button (M-Bus device search). The M-Bus device search dialogue box
appears:
